Through taking on complex deoxidizing and alloying process with ferro silicon manganese alloy in EBT electric arc furnace of Shiheng special steel plant the question of accretion and poor deoxidation in liquid steel is well solved Thus smooth production of continuous casting is ensured,the billet quality is increased,the production cost is decrease

Rapid analysis of silicon,phosphorus and manganese contents in silicon-manganese alloy;

Dissolving sample with nitric acid and hydrofluoric acid,the silicon content of silicon-manganese alloy was made a measurement with ICP-AES method in the hydrofluoric acid-resistant spray devices.
